2017 xj L 2wd portfolio 3L. Had the engine replaced under warranty at 35k miles.
immediately after there was a starting problem that a local mechanic diagnosed and fixed as a finger tight chassis ground strap. I have since been going through it checking things and have correctly routed a hose or two.
This weekend I found a bolt to what I think is an engine Mount backed out. I retightened but wonder if someone has a correct torque spec?
Also noted that all but one of the front splash guard screws to the bumper cover are missing. And missing two of the screws at the rear of that guard where it connects to the next undertray. Looking for part numbers for these fasteners.
Also the lower front of the front wheel well liner fasteners are missing from both sides. Looking for part numbers for these screws.
Up top there are three areas where fasteners are missing. Looking for part numbers for these as well.
Of note, I searched parts diagrams online but the ones I found are not descriptive and vague.
Looking for a good place to order from as well.
Thanks for the help.

 

You really should take the vehicle back. Claim that because there are so much missed parts/fasteners and lose bolts that you suspect that the vehicle are not safe to operate. (here we can go to MOT service to have "offical" 3rd party report)
Obiosly the work has not been made professionally like it should be. None of fasteners should be missing and none of bolts/nuts should be lose. One bolt can be mistage, two indicates that there might be more... As a warranty repair this should not have any costs for you. Contact directly to the boss/manager of the shop, since "workforce" like to hide these and told you off. Managments care their business reputation and don´t like bad words spread. Fasteners and check are cheap for the shop compared the damage you could do the reputation, if you open this to the puplic. (here this kind of careless work would be an authority level case)

 

As mentioned above, first point of call would be back to the dealer, however also moving forward I bought a set of these from Amazon and have found them helpful to keep in the cupboard for various things on the cars.

 

Yes a terrible job and so many things left off!
Your best bet it to use Jaguar's parts system and spend some time finding all those little fittings. I have had zero luck using any so called universal trim clip assortments.
Jaguar Parts

The thing to understand when looking for parts is everything Jaguar does is all related to the last 6 digits of your VIN. So type that in first and start searching you have a number of things to find.
It would help if you could post back what the part numbers are after you find all of them too.
Really will help the next guy as you can see!

Please name the dealer involved so we all know where to avoid.

Otherwise I will just avoid every dealer in Louisiana to be sure.

 

I'd be back at the location that did the work. You've got too many little niggly bits missing. Niggly, but needed! While they are little in size, some are $10 each and also have a two week or more wait time.
If they take short-cuts like this, how does one even know the job was done right? I hate it when mechanics just leave the 'little' stuff off. I have even seen cars with the aerodynamic panel under the car
missing, just because they are paid by the job and not by the hour!
Sorry, not much help.....

 

Ok
With the help of my son who went to palm beach jaguar and showed a helpful parts department worker the under car photos, we have had some success.
c2s545016010 fits the front and rear of the front and middle splash guards
c2z3858 fits the front wheel well screw location
xr87508010 are the clips for the windshield cowl plastic
c2s9354020 fit the front air scoop clips

Still looking for the clips for the jump start location plastic cover
Thanks

 

Thanks for the part numbers!
With so many fasteners it would help if you could add pictures so you can see what it looks like. So many parts places have a drawing or no picture which makes it hard to determine which part is needed.

These were super annoying to find. I actually ended up measuring the points and randomly searching spec, the dealer wouldn't help me with this.
The LR clips fit, same spec, and aftermarket was $9 for like 20 pcs. PN is

LR024316

 

Thanks for that part number. I just ordered some thanks to you.
I will try and get some pics of the parts and numbers.

 

Thank you as there are so many different ones they are hard to identify.

Here is one of the door card fasteners in case someone is looking for these.




There are several similar but different push fasteners again on the door cards.
C2D-3422



And it's almost identical twin.
C2D-3465010



They were so close I had to make some measurements to be sure I got the right part.

I don't have the measurements for this one but it's part #C2P-7160




The Jaguar number for the LR part posted above is XR812941010 common all over EBay for about $8 for 10 clips.

Does anyone know what part number or aftermarket source exists for the fender liner retainers?


They are white plastic clips like this, the fastener c2z3858 goes into them. With age mine have broken on the front undertray.

The middle circle OP posted is some washer/fastener combo that goes into a spring nut. OP made a typo, the PN is C2S45016010.
There is no documentation online about what the fastener actually goes into in the middle section - but mine have popped out of the subframe over time I guess? I believe the PN is C2D20870, but the part does not come up in NA systems? It might be a different part number? I'm ordering from Terry's Jag, as they support XK vintages.
